The world's biggest gathering of iOS developers organized by Apple is happening just a few days before mDevCamp. Peter will be there and will bring all the hot news we should look at in upcoming weeks and months. The talk featured a first in-depth look at the experience of porting http://pdfviewer.io over to Apple's new iOSMac subsystem ("Marzipan").
